Manik engineers provides ammonia liquid controllers in two models [type lc-101 ai and 39fi]. These liquid level controllers consist of a float chamber and an electronic controller. They can be used on all non-corrosive liquids, such as ammonia, toluene, freon, etc. The electronic controllers have a bar graph display module installed to continuously display the rising and falling of liquid level inside the float chamber. These liquid level controllers find its application in various refrigeration applications to control the liquid level. They can also be used as protection against too high and too liquid levels. These ammonia liquid level controllers have technical specifications : refrigerant r717 [nh3], r 12, r22, r502; differential adjustable between 10 to 40 mm3; max operating pressure for float housing 19 bar; and enclosure for float housing ip67 for controller ip54. Type 39fi sensitive liquid level controllers consist of a float chamber and an electronic controller. These liquid level controllers are used to control the liquid level in various refrigeration applications, like flooded evaporators, low pressure pump tanks in pumped recirculation systems, pump tanks in gas pump systems, intermediate coolers in two-stage refrigeration plants, condensers, plate freezers, etc.
